I don't see any benefit of using this over Rust, C or C++. I guess if you have been coding in swift your entire career, it's just one less language to learn if you decide to get into IoT note: even apple engineers hate Xcode, +1 for neovim ( [this video] )

Although opinions inside Apple about Swift vary, they seem to be investing in low level Swift for embedded, kernel use, and programming the “Secure Enclave” subsystem. They certainly have many opportunities to use it for headphones, AirTag, flash driver, etc, beyond the very believable but less embedded use in kernel/Secure Enclave. See also the wwdc session where they propose swift for building smart home thingies [this video]
